To all whom itmtag concern: I

Be it-known thatI, GEORGE-,0. B EIDERT, a citizen of theUnited States, residing at Chicago, "inthe county of Cook and State of -Illinois, have invented certain new and useful Improvements in" Car-Ventilators, of

which the following is a specification.

My invention relates to ventilators, andparticularly to ventilators for cars, or other 10 air-ramming faces arranged transversely to the line of travel of the car and with exhaust openings terminating at the edges of moving structures, which" are provided with said air-ramming" faces over which the air displaced by said ventilator 18 caused to pass so as to create a vacuum which withdraws 'the foul air from the interior of the car.

One of the primary objects of this invention is to provide certain improved arrangements relating to the construction and con-' figuration of the air-ramming faces whereby the air displaced'isqdirected in a larger volume over the exhaust openings and less of it ,allowed to escape over the other edges general character heretofore used.

A further object is to provide certain novel dispositions of the partitionsand deflector plates constituting the "internal arrangement of the yentilator for the purpose of more surely preventing back drafts and hindering dust, cinders, rain, and the like,

from ent'eringthe car through the ventilator and for the'additional purpose of enabling a side wind to operate to effect the ventilation of the car when the latter is at a stand still; the'particular object which these 'constructions and devices have being to provide a valvelessventilator with exhaust passages through which the foul air from the car will pass with a maximum degreeof velocity, the operation of which will not-beeffected by the direction of the wind] The invention consists in the several novel and improved devices, constructions and an rangement-in ventilators of this type here in shown, described and claimed for carrying out the above purposes and such other objects as will appear from the following description of the several typical embodiments of the invention which have been selected for purposes of illustrating the principles of the invention.

Referrin to the drawin s FIOUI'G 1 1s a a I u I U fragmentary view, in perspective, of a car 77 of Fig. 8; Fig. 8,

and l3,'views,in perspective, of two other ventilators showing modifications iii the construction and configuration of the air-ramming faces. a

Like characters of reference designa'te like parts in the several figures of the drawings.

In Fig; l I have shown a ventilator, thedetails construction of which are illustrated in Figs. 3 to15 inclusive, which is mounted on the deck of a car designated 25, the ventilator communicating with the interior of the car through an opening in the roof. The ventilator consists'of a box like structure made up of a base26 having a circular opening 27 therein,animperforate outer end or top 28, and two oppositely arranged. air-ramming faces 29 which are arranged transversely with respectio the direction of travel of the car, thcse'faces acting alternately in accordance with the direction in which the car is moving; Each airramming face is preferably pressed or bent or otherwise formed so as to provide a central V-shaped portion 30 and on each side of this triangular surfaces'31 which are inclined toward the interior of the ventilator from their outer margins to their apexes which coincide at the points 32. The purpose of this arrangement is to deter the air displaced by the ventilator from escaping over the'upper and lower edges 33, 34 of..the air-ramming face and to cause the displaced air to pass instead in as large a measure as possible'over the lateral edges 35, the configuration being preferably such that the edges 35'do not project outwardly quite as far as the V-shaped portion 30 of the face.

The box like structure above described is mounted on a cylindrical element 36 preferably provided with a flange 37 for attachment to the deck ofthe car,- and this cylindricalelement extends up to the top or end wall 28 and is cut away opposite the airramming faces to provide exhaust openings 38 which discharge into the spaces or passageways 39 within said faces. The cylindrical element is bent out on each side of these openings to form deflecting lips 40. The openings 38 do not extend down to the base 26 so that water, dust, or the like, which may be blown into the passageways 39 is kept from entering the car through the opening 27. Preferably rims or flanges 41 are provided at the lower edges of the openings 38. Arranged in the open sides of the ventilator are louvers or deflecting elements 42, 43, 44 which increase in width toward the center of the car. .T he purpose of these louvers is to prevent a diagonal wind from blowing into the car through the openings 38.

I do not lay claim herein to the particular internal arrangements just described, this application claiming specifically the arrangements for the interior of the ventilator which will be hereinafter described.

In Figs. 2 and (3 to S inclusive I have shown a different internal arrangement of deflectors and partitions, a different config uration for the air-ramming faces, and also an arrangement by which a side wind may be utilized for assisting the air displaced by the movement of the car in producing the exhaust. The device, in this case, is shown as operating through one of the deck windows of the car, designated 45 in Fig. 2.

Secured to the base 4t) is a neck 47 whiclt may be secured to the clercstory of a car over one of its deck windows. The base has an opening 48. The air-ramming faces 49 are pressed or bent so as to provide \l-shaped portions 50 and triangular surfaces 51 which are inclined toward the interior of the ventilator from their outer corners to the lines sis of juncture 52 with the /-shaped portion. This configuration, it will be seen, checks the tendency of the air displaced by the-ventilator from slipping over the edges 53, 5d and so being wasted. The exhaust pas sages 55 which extend through the ventilator-inwardly of the air-ramming faces are defined by angular elements, the interior portions of which, 56, are parallel to the oppositely disposed portions of the air-ramming faces, so that the "cross sectional area of the discharge passage-is kept substantially uniform except at the middle, the exterior portions, 57, of said elements being preferably wedge or V-shaped. Ilhere are two of these elements, one at each side of the ventilator, and they are spaced apart so as to. provide exhaust openings 58 throu h which the air from the car is discharg d into the passages 55. By giving the V- shaped configuration to the portion of the structure designated 57 the egress of the air from the car is facilitated and if there be a side wind it is deflected into the passageways 55, and while diminishing the vacuum produced by the motion of the car on the side of the ventilator at which it enters, tends to increase the force of the exhaust at the opposite side of the ventilator. If

the car is stationary and there happens to y be a side wind, this'wind operating against a V-shaped side member, will produce an exhaust through the ventilator, although not as strong as that provided by the air-ramming face when the car is in motion. The outer end, 59, has preferably the same configuration as the air-ramrning faces so that if there be a strong side wind blowing against this surface it is directed over the edges (39 of this face. The elements 56, 57, do not extend out to the end face 59 which leaves a space or passageway (31 extending through the ventilator along the inside of the end face 59 which communicates with the interior of the car. The passage of air over the edges (50 produces a suction which helps to withdraw foul air from the car. The exhaust passage (31 is separated from the exhaust passages 58 by partitions 62.

In Figs. 9 to 11 inclusive the outer end 63 and the air-ramming faces (54 have preferably similar configurations as in the construction last described. Each of these faces is bent or pressed so as to provide triangular surfaces 65 which lie in the same plane with each other and on either side of the triangular surfaces65 a pair of triangular surfaces (36 which are inclined out-- wardly from their lines of juncture ()7 with the surfaces (35. The ventilator is provided with the usual base 08 having a central opening 69. If need be the ventilator is mounted on a neck 70. In the open sides of the ventilator are angular structures, the interior portions 71 of which are given the same general configuration as the air-ramming faces, the exterior portions 72 being preferably wedge shaped as shown. These elements are spaced apart to provide exhaust openings 73 and are formed with deflecting lips 74. The openings 73 do not extend to the base, thelower edges being preferably protected with the flanges 75. \Vithin the exhaustpassages 76 are arranged the obliquely disposed louvers 77. These louvers prevent an oblique wind from blowing into the ventilator through openings 73 and also direct any wind that may blow through the passages 7 6 outwardly away from the opening 73 so that such wind does not have a tendency to choke the openings 73 as-might otherwise be the case. I do not claim herein the arrangement of the louvers in the exhaust passageways of'the -ventilator, as this lit arrangement is claimed in my co-pending application, Serial No; 763,047, filed April 23,1913,

It will be understood that any of the ventilators shown herein might be used either in the position shown in Fig, 1 or that shown in Fig. 2. If the ventilator just described is placed in the same position as the ventilator shown in Fig. 2, and if the air in the car contains a great deal of moisture, there is a chance that condensation will collect in the space within the lower one of the elements 71, 72. To prevent this the -V-shaped portion 7 2 is formed with an aperture 72. This device for freeing the ventilator from condensed moisture might be used in connection with the other types of In Fig. 13 the air-ramming faces 81 are fluted, the flutings terminating atthe edges over which the air is sought to be directed.

While I have described my invention in several preferred. embodiments, it will be realized that further modifications might be made without departing from the principles of the invention.
